[Scilab-users] How to start with several variables in AUTOMATIC function of GROCER

[Samuel Enibe]

Dear sir,

I would like to employ the AUTOMATIC function in GROCER toolbox to perform
automatic regression starting with a rather LARGE set of variables and
ending with the few that are most significant. However, I have noticed the
following problems using the example attached:

1. Programme works with only 3 initial variables specified (see line 30 in
attached file), which works, but line 31 with only 6 starting variables
complains of TOO MANY EXOGENOUS VARIABLES
2. When it runs with 3 starting variables, the R2 value is not specified.
How can I get this calculated and used.
3. The help files included with the AUTOMATIC package does not seem to
answer these questions.

ANY ASSISTANCE WILL BE GREATLY APPRECIATED
